Yes, I scaled up the floats 170% from the Rufe kit.  I made one other change.  As per stats on the real planes, I increased the wing span to 30 inches.
On a slightly different topic, but for info on keeping things light... I will share the following:
I just bought a "Golden Age" kit from ebay.  It is a 24" Kawasaki "Tony"  I just scaled up the plans and copied and enlarged the part sheet (One sheet)
Here is the kit:

This is NOT a kit for beginners.  I already broke one piece of balsa just looking at the parts.
I photo copied the part sheet (I put the balsa sheet on the copy machine) 120%. That will give me a model with a ws of 28.8 in.  and 1/16 scale.

The Staples Store enlarged the plans on one sheet for less than 4 dollars.
Here is the plan with the Guillow Zero wing bellow:

Notice the delicate construction of the "Tony"  The tail is VERY light and the plane has much more dihedral.
I show you this, because I believe these things are easy to do in a Guillows model, and for rubber power, that is what you want.
Here is a picture of the "Tony" someone else built.  This was at WestFAC IV:
 
With the plane slightly larger, it will fit in with my Guillow collection well.

PS I bought the kit for $16 + $8 s/h.  I since found out Golden Age has a website and the kit is availablee today for $24.  They have a lot of kits available.  
***WARNING*** These are NOT kits for begineers.  Guillows makes very nice kits that are easy to put together.  I show this model as information for those who want to make your Guillow kits fly better.
