66' points to Electronic ignition help

Hi all. Sorry to be redundant since there are several threads on the electronic ignition upgrade, but all the ones i have read have been about post-70 vehicles, or have ended up in a several offshoots as to what ignition is better etc.. I get confused easily.

I guess to simplify: If I replace my 1966 points system with the Mopar E ignition, can i keep my alternator and just replace the mechanical voltage regulator?

Is it worth the $100 or so and an afternoon to just upgrade both the voltage reg and alternator to the the newer system or will this run fine for mild street use?

I already have the orange box and e-distributor installed so it's not a question of which ign system is better etc.

I appreciate any input in advance :)
