Tubeless Coker tyre idea

I thought I could save some weight from the enormously heavy Coker wheel
by going tubeless. 'NoTubes' ( www.notubes.com ) sell a 'kit '
(http://www.notubes.com/notubeskit.htm)  which you can use to convert a
standard tyre and rim into a sealed, tubeless tyre. It consists of a rim
strip to seal the spoke holes, valve core and sealant. Has anyone tried
using this kind of system on their Coker?

I've already emailed the NoTubes people and they've indicated that 120g
of sealant will probably be required.   If this works it'll be great,
but I have a few reservations. The first is that the wheel might
actually end up weighing more than when I started. (What does the Coker
inner tube weigh anyway - in grams, please!). Also you have to keep
adding more sealant every so often. And thirdly the bike shop guy told
me that if your wheel has side-to-side flex in it (which almost all
non-wide hubbed-Cokers will have) then the tyre bead is liable to pop
off, resulting in a flat tyre and a big mess of sealant everywhere....

...Having said all that, is anyone willing to be the guinea pig on
this??!?:D
