for me? if you really want the new bed(s) to have lily's in it/them, then I would place the pots with the lily's right in the beds and cover them with dirt. just plant the pot! maybe leave about 1/2 inch of the rim exposed for easy removal later. ive done it many times in the past and no one is the wiser. I wouldnt risk uprooting bulbs that have already been planted. not at this point anyway. just leave them to finish out the season. I dont think it would necessarily harm them to replant them now, but I dont think they would benefit from it either. but since they're already on their way up, I would leave them in their pots and call it good. then yeah, replant them how you'd like in fall.
