It also depends on whether you consider it worthwhile to waste an early blueprint on Ryuuhou considering her subpar stats and plane capacity. (But of course aesthetic reasons trumps all)

You only need to clear 6-1 once in the same way as the early easier maps. (You don't need an S Rank) so you can probably get by with the 1CLT,1CL,1CV(L), 3SS fleet that some people use to clear the Bm1 quest
