Hrm, I have a wizard who takes great personal pleasure in the martial arts but I always assumed that those types of wizards with militaristic backgrounds were xposed to some military force or a sword tutor or something that trained them. As a result I simply trained his Str and dex and dumped other things to make up for it. whereas a sage wizard without that background would dump the physical stats in favor of his mental ones.
As to prioritizing spel selection. the later editions solved this by simply reducing how many actual slots you had to memorize 0 levle spells. a first lvl wizard has 3 and it maxes out at 4 in path finder. You don't get bonus spell slots for level 0 no matter how High your int is, though there are other ways of increasing it in that game.
I also meant to ask, did you mean proficiency originally or both proficiency and damage bonus? Proficiency with a great sword 2D6 vs say a staff 1D6 is fair enough but,, and I'm not criticizing anyone in particular here cos I found it hilarious at the time,, but a wizard with next to above normal strength and who's desc is rped accordingly to be weak, sickly, small of stature what have you wielding a great sword seems anatomically... not right when I visualize it and such things ought be relegated to the realm of anime where you believe everything because reasons.
Your right that ray of frost and acid splash don't do much damage though:

The latter part of that fight is what i'd expect from a military wizard. it's a rat, beat it to death. The prior part is what I'd expect a sage wizard to do. I'm kind of curious what you can do with the proposed spell that you can't with a high str and a weapon proficiency feat is what I think I'm getting at. Would it also be be fair for a wizard to overcome these costs with a level 1 spell that in the proposed version could be made persistent in which case it would negate much of the cost in giving it a short duration.
Cantrip damage would need to be upped to keep up. I'm not sure how much hp these dire rats and such have but your lvl 1 wizard with 3 cantrips and 1 lvl 1 spell should be able to deal with at least 1 with his full repetoire since I see both types represented here have 5 hp:

If they rolled minimum on each hit I suppose they would be left with an angry dire rat at 1 hp but... well, I relegate such things to tabletop antics.
by making cantrips unlimited but limiting level 0 slots severely you also eliviate the pressures of FK wizards to invest in stats that they may not want to simply because they don't have the patience to spend hundreds of hours from lvl 1 - 16.
Anyway to summarise, I think you can already achieve what you want by making the choice and dumping mental stats for physical ones. My fighter uses a 1D6 weapon and outdamages people who use 1D8 and 1D10 because his bonus +damage is higher and will consistantly do more damage with his saber more than someone else can do with his or her bastard sword. Weapon proficiency won't help you in the long run excluding getting your hands on an incredibly heavily enchanted weapon. Moresoe than your +2. Lastly, why not just use true strike? The FK version lasts more than 1 round and I assume will grow lengthier with practice. the main detracter being that You will need many instances of it to be viable right now
