Awesome WM and XFCE

Question

dear Awesome team! I just wanna ask you, will any problems be if i use XFCE and Awesome wm on my Debian Linux? 2 actions can be:

1. I use Awesome WM as defautl WM of XFCE insted of xfwm4.
2. I use Awesome WM and XFCE in differents sessions.

Can I get errors or problems with these 2 actions.

P.S. I very like your Awesome WM and I just wanna use it but possible problems stop me.

I have not tried yet. I just wanna ask to be more prepared for installing Awesome WM on my Debian Linux with XFCE.
