Would it be possible to switch my battery adapter plug from the old PBG4 Style to the new magsafe style? Of course with a little rounding on the case with a dremel.

No.

Same idea, different laptop.

A power connection is generally pretty simple - just +/- connections (two wires). Splicing together a MagSafe and an old-style power adpater may be difficult, especially since the old-style adapter uses an RCA-style plug, where the wire is probably coaxial style (positive with negative sheating around it, with an insulating layer between the two).

However, if you can figure out how to solder a MagSafe connection to your PB's logic board, it should technically work. Have fun!
