What should I breed my "mimosa" with?

So a pastel hypo enchi male would be a good bet?

excellent choice.

you have a champagne (dominant) hypo (recessive). since hypo is recessive, the male should at least be het hypo, if not homozygous hypo. otherwise you would only get hets, no visual hypos. since it has champagne, the male should not have champagne, spider, woma, or hidden gene woma in it. (you get the lethal combos when you try to combine two genes that are known to have the wobble)

and enchi just works perfectly with champagne, it brings back some pattern to the champagne, enchi champagnes look really interesting. and since this is now well-known, enchi champagne combos are really popular and in demand.

so yes, a hypo enchi is quite ideal, pastel hypo enchi is even better.
