Dunno, but  some  10-50MHz TCXO/VCTCXO are now available in 2mm 
packages, so why not.  There might  be battery longevity issues with 
driving the higher frequency.  I guess it comes down to whether the 
maker can sell enough to make a profit.
FWIW, My Citizen Chronomaster is has gained just 1,8 seconds in the last 
12 months , well within the spec. of +/-5s.
