I dunno. I kinda prefer that it's totally separate. I smell serious future drama when someone leaves a clan with 200,000 strategus money (which I'm sure some people are sitting on that and more right now), converts it into 2,000,000 cRPG money and yuks it up on the forums.
Granted that does happen in EVE now and then.
Maybe what we need is a level of visibility. Create a "view transactions" permission which clan leaders can assign to clan ranks. You can then click on a clan member's profile and see their transaction log: money in, money out, where it came from, where it went to, and a timestamp.
That, at least, would let us keep tabs on our clan's cRPG cash stash.
