I just moved into a new house and while the layout is perfect for my modern-ish goals, lots of the details are very builder grade. In this case, all the doors are you're basic 6 panel composite doors.

I looked into buying modern doors with no panel design (a flat, smooth surface door) but they get prohibitively expensive when they're not hollow.
Is it possible to use some sort of putty or other filler to fill in the panels and not have to replace the door?

clarification

Ron,

Sorry I may not have been clear enough. I do not currently have hollow core doors. I have the 6 panel doors. I am asking whether i can use some sort of filler to fill in the panel design on the doors. The end goal is to make the door look like the more expensive modern, smooth finished doors.
