I know, bad form to reply to my own post, but I just discovered
that my brain was fried last night :-)

  However, it
appears that 3 off 2.5Ah Cyclon cells would fit in the 
housing. Has this ever been tried, and does the HP charger PCB charge 
these correctly without damage? 
The 1.5 V difference is  big enough that the charger may actually
damage them.  Low duty lead-acid batteries are supposed
to be charged using constant voltage (with initial current limiting,
one amp for the ones in question).  For standby use the charging
voltage for these is 6.9V; for cycle use the charging voltage
is 7.3V .  Both are way too high for a 4.5V nominal pack.  And
I think that 4.5V is probably too low for the hp9114. 
It should work -- 3 cyclon cells = 6V, the required nominal voltage.
But I would still try to get the LCR062R4PU's.
