I can understand to a certain extent why the Privaron Espada were brought back though (strongest non-Espada Arrancars). Charlotte possibly for that Rosa Blanca/Ruri'iro Kujaku combo you mentioned. Luppi... well he was briefly an Espada... that counts for something I guess ? And I do agree Rudbornn would've been a good choice of Arrancar to resurrect, although it was never confirmed if he actually died if my memory serves me correctly.

I can see why Mayuri might not have resurrected any of the Espada. Baraggan, Ulquiorra and Zommari disintegrated. Yammy and Nnoitra are bestial animals (too much like Zaraki for Mayuri to bother with). Szayel offended him. Aaroniero... well, yeah. As for Starrk. Well, having Starrk would be pure overkill; Starrk alone would mean there'd be little to no point in bringing any other Arrancar (so the plot says no to Starrk).
