I say go for it and have a blast doing it.
I think it’s awesome when people breath new life into a any old airplane.
I purchased my 70C as a total runout back in 95. I practically replaced every nut, bolt, rod end and all other components you can think of.
I did have a AP / IA that worked with me during this process which I think is a must, it will save you a lot of $$$$$$.
Some Of the (best) mods I did are flap seals, cowl closure, power flow and three blade prop , all combined helped immensely with climb on hot days.
Every where I land I always get compliments, every shop that has annualed it since my IA retired is stunned with its condtition.
I hear many that say it’s only a C, you will never get over 40-50K out of it, I call baloney. I’ve been offered way north of that many times just by word of mouth with locals in my general area.
I had so much fun over the years restoring my C I got very bored afterwards, I’m now pretty far into building my Vans RV-7 which is another fun build...........
