low-Magic Game. Costom weapon Help

[Nosta]

I am Running a low magic game at the request of my players
and have taken to alchemy and others to make the game feel totally not weak

I Remember in my first game my fellow player had a sword-bow

and I was wondering if it be conceptually plausible to make a short-sword/hand cross bow weapon and if so how do I stat it.?

[Gildedragon]

Couple options:
1) a bayonet on the xbow (complete scoundrel iirc)
2) the MIC has a crossbow that turns into an axe. Difference between an axe and a short sword is not that big.

Hope that helps
