If you want a 3.5" 27 then you should buy one. You will spend a lot of money to wind up with a less than fully satisfying gun trying to make a 28 into what you want.
Really, the 1/2" all that important? I have N frame 357s in both 3.5" and 4" and you never notice the difference unless you turn the gun sideways and look at it.
This made my FAQs.

\Modifying a gun into a different configuration.
33. Trying to turn the gun you have into the gun you want is never a good idea. It will be cheaper, faster and easier to sell the gun you don’t want and buy the one you do want rather than try to alter or convert your gun into a different configuration. In most cases the alterations suggested are not possible due to physical limitations and if they were doable the cost of such work would be beyond all but wealthy fools who like to throw their money away.
