An American wheat could be anywhere from 30-100% wheat malt but likely something closer to what @sneezles61 said. 50% pils and or 2 row.
That cane syrup will most likely be more like using molasses than other sugars since it's less refined. It will leave some residual flavor which could be sweet and similar to honey. Hard to say since I've never used it.
Sounds interesting. If the brewer will share some info you'll be in biz, otherwise just trial and error til you get close.
