Combat archery is very doable. Especially with the powered up bow bash (if you hit with a fully drawn arrow, if your next attack is a bash (and it's quick... less than 4 seconds or so) you'll do bow damage with the bash. That said, if you use bound bow, you'll ALSO be leveling your conjuration.
Before a fight, you can cast a flesh spell, summon a minion then cast your bow. It works better than people seem to think. That said, I'm not so sure you'll really be able to use destruction too. There's still plenty of options though. Illusion is a good (though magicka intensive) compliment to conjuration, and with alteration (for flesh spells) you'll be able to paralyze at higher skill levels.
Restoration is good for healing AND messing up undead. Really your only "combat" skills will be light armor and archery. You won't need smithing (except arcane) because your bow is summoned. At level 35 your build could look like this:

That leaves you plenty of levels to figure out what other skills you want, or to continue on the paths already laid out.
P.S. Didn't put any perks into sneak... my bad. Try this at 40.
