B body interchange question.

I know a lot of you guys are B body experts. I recently discovered a 69 charger (a customer's neighbor's). It's nothing special, but it is none the less a 69 charger. It's a F8 318 auto vinyl top car. Been sitting since '82, and fairly clean. Got parked next to garage by dead junky kid and left for 37 years. Nose is crusty, but the unibody is clean(quarters, floor, trunk, roof, ect, everything else is there too(trim, lights, everything, keys in ignition). He literally parked it, OD'd, and time went on.

I know B bodies are stupid expensive, but a 69 charger doesn't float my boat. Can I convert this to a superbee or roadrunner(70 preferred)? If not is a 68 or 70 charger nose swap possible?

I know this is sacred Duke boy's ground, but I never did dig the split grill General Lee.
