Three, not necessarily mutually exclusive options I'd like to see for Alliance ships:
1) Variants of existing or older craft. The Alliance doesn't have centralised shipyards, it's a collection of fleets from individual worlds so having the exclusive versions of existing craft which can only be purchased from the manufacturer with an Alliance military rank kind of makes sense for this. A centrally agreed contract with manufacturers which is open for members to opt in or out of is totally in keeping with the Alliance doctrine.
2) Modular builds. Similar to the above but with the variants being the result of modular add-ons or units made by individual member worlds representing the diverse internal market of the Alliance with dozens of manufacturers producing their own version and variant of a ship module made to a common set of standards. This would be awesome but probably way more work than FD have put in for the other two factions navies.
3) Grey, Octagonal and with non-Newtonian thrusters...
