make old mods that are no longer supported by developers work with new ksp versions

[Tuvok]

In ksp 1.8 kerbal engineer  is no longer compatible so I still use ksp 1.7.3 , I do this for other mods as well squad please make mods like raster prop kerbal  engineer  that are no longer supported by the developer  compatible  again.

wait, I use Kerbal engineer and it works just fine, on 1.8.1

Squad literally cannot do this. At best one of the programmers could adopt the mod in their spare time and work on it for free - just like any other person could - and that's assuming the mod's license allows it. KER's does (the R was added when someone adopted it from its original author after all) but not every mod does.

And you'll get no more guarantee of extended support that way. It's better to just use what you get, make what you need but can't get, and live with what you can't make or get from others.
