megtenné

Usage notes
This form can be used to introduce polite requests, e.g. Elnézést, megtenné, hogy készít rólunk egy képet? (“Excuse me, would you take a picture of us?”, literally “would you do it that you…”) In the subordinate clause (the main part of the request), the verb doesn't need the conditional mood anymore (cf.  rólunk egy képet?).
