A high power 2WD setup will probably be okay for you. I would pay attention to trucks and whatnot, don’t use cast parts, only billet machined parts. Don’t use 8mm axles.
I would recommend maximizing (within practical limits) your gear ratio, definitely be looking in the 5+ to 1 reduction range and not huge wheels.
Low Kv motors can have their own share of problems, but are sometimes useful, but more advice could come from answering the goals questions above.
You need to start with a deck and enclosure though, and you will need a strong one of each. Deck flex will knock out a 3D printed enclosure in no time at all, you want fiberglass. You can’t really design anything until you get the deck and enclosure down.
