Playable - possibly even systemically superior.  But it's also playable 
to agree that pass is non-forcing and X shows extras for the original 
t/o double.  The LAs rather depend on what methods one discovers the OS 
to be playing (or attributes to them if the situation is undiscussed).

My own agreements are that forcing passes apply only after our side has 
freely bid a vulnerable game (this sequence doesn't qualify) and, IMO, 
that is rather more of an agreement than is typical amongst UK pairs.
With a rabbitty pair I don't think an AC would even stop to consider the 
possibility that they might have had a forcing pass agreement.
