All right, if it's temporary, that works for me.
(what is the future tense of "can" in English, in the contexts where "be able to" is not a valid replacement for "can"?).
Present "can" is actually the most idiomatic wording here. "will be able to" isn't invalid either, though maybe a bit unwieldy with the passive. I think "once we do X, we'll be able to do Y" is a pretty common construction. The simple present "can" is I think always valid in those contexts, though. The meaning is probably about the same but maybe a little less stressed.
