Yes, it is harder to handle the transition of voiced B to unvoiced T than it is to handle the transition from unvoiced P to unvoiced T. If you try to voice the B, you will likely end up with a voiced D at the end “Debd”.
It can be done with lots of practice but native speakers don’t normally do this.

That's a bit strange, since the vowel is already voiced, but I do believe you - it just goes to show how complex our vocal apparatus and systems of pronunciation are.
For what it's worth, "bt" is not a common combination in my native Romanian either, but it is not hard to pronounce.
