Part Suggestion: More methane tank and structure adapter options

[byaafacehead]

One small gripe I currently have is the lack of MK2 to small diameter adapter for methane-only fuel tank when building airplanes. There's a decent selection of methalox adapters so really just having methane and structural (e.g. no fuel) versions of those adapters would be nice, as currently the only option is to use a methalox with no oxidizer.

Fairly minor but also seems like it could be pretty easy to add.

 

Edit: also I realize tubes do offer a good "procedural" adapter solution for structural only. So definitely those are nice.

I just want them to make the feul tanks procedural. The MK2 and MK3 tanks would be only procedural in length and the regular tanks in length and stepwise in width (so XS, S, M, L, XL). Then just add a part switcher between methane only and Methalox (Same can be done for hydrogen)
