Upgradable parts, specifically motors?

[Demigod]

Are there any mods that allow upgrading of rocket motors? If not could someone who know how make one please

I don't mean use it x number of times and it improves. My idea would be something akin to fallout 4s weapons system. Start with a base engine then as can use science and or kerbal experience to unlock different parts for that engine. Different engine balls, new gimbals, exhausts, thrust chambers, engine controllers. Each could have different affects on the engine/motor better thrust, fuel consumption, reliability (if failure mod used) heat resistance for long burns etc, while also visually changing the engine. 

 

I would love to make it but I haven programmed anything but basic and a little c and not in more years than I care to recall.

Is this idea even possible in kerbal?

I know its a lot of work. but if any one like the idea please run with it I would like it

I was gonna recommend using the stock docking system or KAS/KIS to switch out parts as you get better parts from the tech tree.

Looks good but still isnt quite what I wanted. 

Perhaps Its easier to just say I want to make my own engines from different parts?

Adding stats at the end game will make the game last longer but I want some actual engine development. Perhaps making simulating launches into testing while rather than sort of cheating

 

Thanks for the mod link though

There was a discussion thread around here somewhere about a procedural engines mod. Maybe look in there?
