Beaded gloves opinion

I’m gathering things to make these Princess Bride Fingerless Gloves for a friend of mine.
I’m doing them in T.A.R.D.I.S. Blue with white beads.
The opinion I need is the type of beads.
I’ve got plain white 8/0 beads like it calls for. It also calls for some crystals and other shaped things that are 6-8mm beads.
Do you think I need to find beads of that size to go with what I have, or can I get away with using the simple white round beads for everything?

I’d go with one type of bead because the lace pattern plus beads is intricate enough. They’re very pretty gloves and will make a wonderful gift.
