There's a Bike Friday New World Tourist (size Small) for sale on this forum that might work for you. We used our Bike Friday Pocket Crusoes for a long unsupported tour in 2004 and have since used them for many utility rides to the markets. You're not that short at 5'4", so I am not sure that you need to go custom.

Here's a link to our bike tour report if you want to see Bike Fridays in action on an unsupported, fully loaded tour:

Good luck!
