Could you install some kind of trim to hide the pocket hole screws. Or maybe a tool holder of some kind on that end, maybe peg board or slat wall. Something functional maybe. Other wise I am with the bondo and paint.
www then youtube.com/watch?v=k5VAxqzkmX4 for the dowel method.
I've done this once where I couldn't hand drill the hole deeper. I used a regular twist drill and drilled the end of a dowel to form a v-shaped indentation in the end. Put some glue in the exposed pocket hole, then put the modified end of the dowel into the hole and tap it tight against the head of the screw. Let the glue set and trim off the excess dowel with a flush cutting saw. Sand and paint. If there is a very small opening after sanding fill it with wood putty.

I generally use the Kreg plugs...glue them in and sand them flush.

The most expensive tool is the one you buy "cheaply" and often...
Could you let the visible pocket holes be part of the design?
With a $20 - $50 Kreg jig, you could drill pocket holes in some sort of an interesting pattern.
I'm sort of kidding, but there's a bunch of possibilities to do something totally unique.
Otherwise, did anyone mention Bondo?
