One of my players is a Trandoshan and tends more towards brawn than anything. Probably no great surprise. Anyway, she was curious about the potential for using brawn for some mechanics checks in the 'if it doesn't work, try hitting it' school of fixing things. Important to note that there isn't another player who has shown much interest in trying to fix things, so it isn't a case of taking away an Engineer's time to shine.
This is what I came up with as a starting point, any input would be appreciated. Excuse the wordy wording
Forceful Mechanic 5 or 10xp
You may use brawn for mechanics checks, and upgrade the check once per rank of Forceful Mechanic. Upgrade the difficulty of the check once for the 1st, 3rd and 5th level of difficulty and add a setback for the 2nd and 4th.
so if it is a simple check it'll be a red, for average, red, purple, setback and so on. Basically rolling a despair will result in some sort of breakage
