It would do the job, but a Size 40 would be the better choice.  Assuming your asking for Jib/Genoa sheet use...

Mitch and anyone else who's interested,

I'm clearing out a bunch of Lewmar gear from my sample account. 

I don't have any pairs of winches, but I do have some single winches at bargain prices.

1 new #40 EVO Series Grey #49540057                                     $671.

1 new #40 CST Ocean Series Chrome #49040056                     $767.

1 new #40 AST Ocean Racing Series Grey#49040040               $788.

1 new #16 CST Ocean Series Chrome #49016006                     $401.

1 new #15 EVO Series Black #49515055                                     $362.

Shipping usually runs around $20 a winch.

These are all new winches that I have used as displays for shows and winch repair/servicing seminars.  I'm sure Bud can get you a mate for any of these.

I have these on EBay at higher prices, so if you want these prices contact me directly.
