I suppose this question was always valid, although it seems starting this particular new wave it becomes more acute, mostly because...
1) Limited availability of the expansion packs
2) The Jedi never flew entire squadrons of Delta-7s, the way the miniature stand looks
3) This is a fairly uncommon situation of a single expansion pack containing far more base plates than you need for the matching miniatures in the same expansion (4x Delta-7 base plates)
Particularly #2 makes me think - I mean, during the Clone Wars, it was basically always one Jedi (Padawan, Knight, or Master) leading a group of Clones operating as a unit. And if you arrange the minis on the stand that way...well, you've suddenly got PLENTY minis to use all the Jedi base plates the expansion ships with.
IE., with a single 'Republic Squadrons' expansion, you can do this...
But...my Lord, is that... legal?
