Demon Clone Project

I'm finally going to start a project. I plan to make a Demon clone from my "wreckage" that's sat around for years. My first decision is which car to use. Yes I am asking questions in this thread but it should turn into a resto thread. If I'm wrong to post here let me know.

1st car: 73 Duster /6 (blue) (good powertrain, good interior but wrong color) crashed by daughter, parts car only - driver door & L quarter pushed in bad (fortunately no serious injury). I likely won't use much and should part it out (maybe daughter will help, learn and earn since it's hers).

2nd car: 73 Duster (yellow) Was a 340 4 speed with folding rear seat (not my favorite color - golden brown), making it kinda special. No powertrain. Have 73 340 and later 4 spd with od from truck to replace. Problem is both front frame rails have crash damage. K member bent on R. Roof was vinyl, with typical rust resulting, no perforation but pitted. Small rust area R lower quarter, passenger floor pan bad, otherwise very good metal. I have a complete front 73 clip and have been planning to splice it on. I also have all the front end parts from a 72 Dart to make the Demon clone. Use K member from Dart Sport (below).

3rd car: 74 Dart Sport 318 auto (brown). Powertrain intact (removed). Bucket seats, and rear seat good except bucket seat bases need recovered (nice parchment color). Spare rear seat cover came with car. Had vinyl roof so also rusted, not as pitted. Main problem is L quarter has been bondoed, now with lower area rust. Bondo goes to driver door, 1/8" thick in places, actually very nice job but I would replace this quarter if I used this car. Needs partial floor pan (driver side).

Here's my non-negotiables.
It will have a Dart/Demon front end.
It will have a 340 and 4 speed.
Color will be 1973 Mist Green (or Meadow Green). No vinyl top. No stripes.

Goals - enjoy the build - make it look how I like it - build 340 to sizzle tires (350 hp?), summer cruising, 1/4 mile, not a daily driver, not a show car.
Budget - cost concious, just what it takes to do a nice job. Resale value is not irrelevant but not a primary consideration.

Option 1: Splice 73 Duster front clip. Keep folding seat (recover with parchment color). Recover bucket bases to match. Leave tail panel in Duster version. Keep Duster front sheet metal for potential future re-sale to someone who may want to restore to original.

Option 2: All the above but replace tail panel to take Demon cloning further. I like the Demon tail panel. Seems to me a clip spliced Duster loses any real re-sale value anyway.

Option 3: Use the Dart. Cut up the 73 340 for the quarter and 4 speed floor pan. Sell folding seat etc. (not sure if it's even desirable).

Option 4: The above but transplant folding seat into Dart (I kinda like it).

I have more confidence replacing the front clip than the quarter. Maybe because I've thought it through and can visualize exactly what to do. My mig skills are just OK. I have a friend who is excellent to weld the frame rails. Quarter replacement spooks me for some reason and maybe it's silly but I feel reluctant to chop up the 340 Duster even though it will wind up being a chopped up car if I use it.

Of course there is no right or wrong way but I'm interested to hear opinions on these options. I'd like to know which option folks think provides better resale potential even though that's not the primary consideration. I suspect the Dart with replaced quarter may have better value than the 340 4 speed Duster with spliced clip. If I do the Dart I'll feel free to swap to a Demon tailpiece.

Ya, I know, just make a decision and do it, right?
