I would keep it simple and do no more than 3 layers of bulbs that succeed each other in flowering times eg tall tulips in the bottom as they require the deepest planting depth and will flower in April/May, then daffs for March and crocuses for February.
Bluebells are best naturalised in a woodland corner under trees or shrubs. Snowdrops don't like to dry out so are also best in the ground where they will also spread themselves. I find hyacinths have such a strong perfume they are best in a pot by themselves so they can be brought into prominence when in flower and moved out of the way when they go over.
I like alliums best coming up through perennials such as hardy geraniums and they are good plants to put near roses as they help deter greenfly.
