Wouldn't it be far, far easier to manufacture an actual powersword than an article that covers the teeth individually?
To me the concept seems to want the best of both worlds: Desiring the chainsword's enhanced damage potential, with the powersword's advantage of the powerfield. A bit like wanting a sportscar that seats 7. Sometimes there's a choice to be made.
Hence the whole "personalised/signature weapon" idea (one of a kind tailored to marine) including use of wargear talent (500xp) to aquire it.
Also, not heard of the ferrari limo? seats 6 or 7 if i remember
