you will easily add 30g of sealant at a minimum. 60, perhaps, but let's say 30. grand total is 342g if your wheels are UST / roadtubeless ready. if not then you have to install two layers of the stans rim tape and add that.
a conti GP 4000S, very comparable tire to the fusion 3, is 205g. ultralight tube is 75g. grand total is 280g, in fact if you install mr tuffy ultralight liners, that's still only 310g to the road tubeless 342g+.
The lack of tire choices says it all for me. I tried road tubeless in 2006 and these were basically the same tire choices you had then. They will never catch on unless the pro's use them -- however, they have no motivation to use them since traditional tubulars are their first choice when they need better than a clincher.
