It will be great if you can come.

Dear native English speakers,
Would both be used?
(a) It will be great if you can come.
(b) It would be great if you could come.

Thanks in advance.

I think so, but B would be far more likely to be used. I think A would mostly be used in a context where you're expressing appreciation at someone's offer, while B is an indirect way of asking them to do so.
