This is my educated guess.

Judging from the material of the grip on Honda stock steering wheels I don't believe it would be possible, at lease done cleanly. Now if it were another type of material other then what it is, I would suggest taking a heat gun and consentrating it on the particular section on which you wish to bend. After about 5-10 minutes the inner metal brace should be soft enough to mold, but the bad thing is, that after about 4-6 minutes of the heat gun, there's a high chance of the plastic rubber material that surrounds the matel brace of a steering wheel to just melt. leaving you with a very dangerous situation.

Hope this helps.

Cliffnotes: No. Not likely possible.
