Will Elvis have to be protected in the next expansion draft, if he comes over before then, since he's been playing pro hockey for awhile now? And if not, then if he comes over this year and there are 2 seasons until the next expansion, then he would have to be protected regardless.
If the first scenario is true, then it would be better to have him come over now, and if not, then he should stay in Lugano for another year. This is, of course, assuming fall 2020 is Seattle's first season. Not sure on the timeline for that, however.
