I can see what you're getting at - and it's a noble ideal but the thing is, within 3 months, a player can be effective in a Battlecruiser which would contribute well to many types of fleet or would be only shy of a few Lvl 5's if he trained for frigs.
I know that the support skills are a pain because you don't feel the benefit except for fitting or access to T2 mods, but I can't see that will change just because you get to do them quicker.
I suggest that if you're put off by training a rank 1 skill to Lvl 4 within a matter 1-2 days, having it train up in 1.5-2 days isn't going to make much difference to you.
As for the learning skills, that's a whole different can of worms that has been beaten to death, revived, flogged, sold, bought back, buried and exhumed so many times it's just not fun anymore.
Personally I'd do away with the advanced versions in one stroke; good luck to anyone who saved themselves some time and bad luck to those that trained them up high (myself included).
I think the basic learning skills are a fine tool which can be easily used or disregarded with little consequence as they are equivalent to the implants available anyway.
