Clichés are, or can be, a little wider than current skills so converted skills can be added into clichés - eg two or three low value skills that come somewhere close to a Cliché can be grouped, or just plain reassigned.
Three schemes in mind,
1) 'Cliché' dice = (skill + attribute)/2 - round down
(tends to come out a bit high, works best for a straight skill->cliché conversion, no combining)
2) Dice = (skill + attrib - 4)/3 - round to closest whole number
[This is the system I'm currently testing]
skill - cliché
13 - 3
12 - 3
11 - 2
10 - 2
9 - 2
8 - 1
7 - 1
6 - 1
5 - 0
(a bit fiddley - but a straight /4 may come out a bit low - definately needs aggregation, but this tends with the long established characters to lead to a lot of top end - 5 or 6 - Clichés ).
3) I wet a finger in the beer you've just bought me, hold it in the wind and say say "Looks like you have, oh, 5 Clichés playing in a 5, 4, 3, 3 formation", or look sorrowfully at the dismal pickles, shaking my head saying "3 clichés, none above 3..."
The Risus limit of 6 dice to a Cliché applies. Any skill that rounds down to 0 under the first two systems is taken as a experience roll.
Are just absorbed into the skills -> Cliché conversion. If someone wants to make a point of a good attribute such as Strength could take a Strongman Cliché for Sir Fortinbrass-like Feats of Strength (if you'll excuse a cross-reality comparison). Just skim dice from other Clichés or use 0 rated skill experience rolls.
Some of there can be translated directly into 1 or 2 dice Clichés, others will need a bit of discussion.
I'm not sure about using this Risus feature, though it has potential for amusement of course. Dutch Admiraals just aren't the same without their Rifled Ducksfoot-Volley-Blunder-Pistol, most Pyrates wilt like flowers in the desert sun if they don't have a Bottle of Rum to hand and a Bokor without an enchanted bull's-pizzle doubtless only casts limp enchantments.
Slightly more seriously, armour is an important part of one's Conquistador/Gunner/Inquisitor character, who probably would function less effectively without it - see how useful he is stitched into his hammock.
