I thought along the same lines, albeit perhaps a tad more simple... 'Brace o' pistols, very pirat-y, aargh!'If you swap the las for a plasma pistol maybe having 2 makes sense. When it gets to hot you just drop it and draw the next one. Or holster it as it recharges depending on what version you play.
the sword is unfortunately glued in position with super glue. Could be easily moved or replaced.
