Easy way to implement more interesting Repairable Parts

[ZenithRising]

So my brother recently told me the story of trashing his space station's solar panels in a failed docking maneuver, lamenting that panels aren't repairable. I told him that I was pretty sure that more repairable parts were planned, but it got me thinking...

I really dislike the way wheel repairs work, it just feels so abstract and easy, but I do think more difficult repairs on a wider variety of parts could make a really interesting addition to the game. So I came up with this idea, which I think would be fairly easy to implement:

1. Certain parts are marked as "repairable" (wheels, panels, whatever seems logical and balanced).

2. All repairable parts have a grab-point(s) like ladders do.

3. In order to repair a part, an EVA Kerbal must grab it first.

I think this would make repairs non-trivial (and therefore interesting), without making them too difficult. And if you wanted to add a repair animation later, you could do that pretty easily since the Kerbal is already attached to the part.
