I would strongly advise agains this. putting weight on your lead leg and just taking a kick is a horrible idea and will have you unable to walk after 2-3 kicks. You are much better learning how to check or avoid kicks properly, and lets face it. If you cant check kicks, you have no business being in a ring anyway.
That being said, good luck
I think this has been more of short notice advice or I could be mistaken? I agree if you have the time to learn techniques properly than do so, but it seems OP is strapped for time, partners and coaches and with out someone showing you how to check or do techniques properly might as well fall back on toughness and haymakers.
Lets face it though, amateurs hardly throw proper thai kicks anyways. The posture is all off, most drop guard and barely crossface. The overhand right on low kicks is there all day even on some professionals!
