I used to use the bottom bar from an older version of profit for a very long time as I was a mix and match...
But because profit_styles has changed a lot since that version was made, I couldn't use it with the latest version of the Profit Market window....So I took the plunge and have fully installed Profit and am now getting used to my buttons being in different places....but worth it
Aaaaaanyways, yes, it is possible to use the bottom bar, but the top bar is attached to 5 other parts of the UI
