just thinking out loud here, but could a crosscheck be a straight swap for the LHT frameset in terms of spacing, mudguards etc? seems so, with the Gnot-rite spacing (132.5mm) etc
You might need to go a size smaller for similar fit too (unless you need a longer reach).
A 62cm Cross Check is a little over 10mm longer so you'll need a shorter stem, and about 5cm worth of spacers ro obtain a similar fit to your original LHT.
