Instead of making special Stars why not just buy players (line or position, any team..) with starting SPPs (or EXPerience, if you use the new rules), each SPP costing 5% (or even 10%) of original cost. To a max of doubling the original cost...
So if you want a really good human catcher you could spend 140k (instead of 70k) and receive one with 20 SPPs (or 10, if each = 10%), making the apropriate SP roll (s), but no ageing!...
I think this can be a good way of leveling (a little bit) the stunties teams (a halfling team can have a lot of SPs!...), taking SPs to the team roster and history (improving and ageing, that is)...
