You use weapons acc not physical limits for most attacks. Dice pool of 11 basically makes it your secondary attack, which is fine. Increase ability (blades) which you can take one rank in place of increase accuracy adds one to your effective rank into that skill. Making your pool be 8(9) pre foci. Dropping astral perception (for now picking it up as a foci later) would free up 1 PP and 4 skills, letting you max blades as well, and have 2 skills let over, one for blades specialization, and one more for either perception or counterspelling, also drop artificing, with rank you will burn yourself out to make anything, this can be used for specialization for your most common spell type to aid in casting. Taking specialization swords adds +2 making you pool 13 with your katana, pre foci, 16 post. Now you have a decent combat skill pool.
I understand wanting to keep astral perception, but for 13 karma & ¥12k you can get a F4 Qi Foci (astral perception) and 1st rank in assensing. Remember majority of assensing test are threshold based, with 4+ hits giving everything you will ever need to know. Another option is not to get the weapon foci yet, get the astral perception foci instead and free up PP that way, and only having 2 ranks in assensing will get you 8 dice, which will get you decent info. And use the 3 (1 from artificing) skill points for specializations in spellcasting, assensing, and blades.
Edit: enhanced acc is .25 pp.
