Thinking about trying a 3gal BIAB Ten Fidy Clone... is it possible?

Any of you that have brewed smaller batches of big beers using BIAB, please chime in. Your advice would be appreciated!
After scouring the interwebs for recipes, this is what Ive thrown together. Let me know what ya'll think-

mash @ 155 60 min, mash out at 170 10 min
90 min boil
65% eff.

7lb pale ale
2lb munich dark
1.5lb flaked oats
1lb chocolate
1lb roasted barley
1lb crystal 50
.25lb crystal 120

1oz columbus @ 80 min
.5oz columbus @ 30 min
.5oz warrior @30 min
.5oz columbus @10 min
1/2 whirlfloc tablet @ 5 min

Anyone???

Bueller?

i would like to know too. I made a 3 gal. Flying dog gonzo clone and it had more grains than your recipe. I found this link... https://www.homebrewtalk.com/f68/ten-fidy-clone-321584/
It had this recipe for a 5 gal. batch of ten fidy...perhaps we can use this and multiply by .66.

12 lbs 13.8 oz Pale Malt (2 Row) US (2.0 SRM)
3 lbs 10.1 oz Munich Malt - 10L (10.0 SRM)
1 lbs 15.3 oz Oats, Flaked (1.0 SRM)
1 lbs 10.8 oz Bitish Crystal 53L (55.0 SRM)
1 lbs 10.8 oz Chocolate Malt (450.0 SRM)
1 lbs 6.4 oz Roasted Barley (300.0 SRM)
1.12 oz Columbus (Tomahawk) [14.00 %] - Boil 80.
1.12 oz Columbus (Tomahawk) [14.00 %] - Boil 25.
1.00 Items Whirlfloc Tablet (Boil 15.0 mins)
1.12 oz Columbus (Tomahawk) [14.00 %] - Boil 10.
2.00 tsp Yeast Nutrient (Boil 10.0 mins)
1.0 pkg American Ale (Wyeast Labs #1056)

2 options for increasing efficiency is to pour some water to use as a sort of sparge, or save some water to dip the mashed grains in after the mash. Then squeeze the **** outta that bag when you're done. It should work great!

I am not sure about a 90 min boil for smaller batches, everytime I try this I lose too much volume to boiloff.

Thanks for the responses. @70ls1nova, your grain bill X.66 comes to 15.3lbs for a 3 gal batch if I did my math correctly... what was your OG? I realized I scaled my recipe down wrong, so the grain bill is actually:
7.8lb pale
2.4 munich
1.2lb chocolate
14.4oz barley
14.4oz crystal
which comes to 14.4 lbs, and (according to my brewpal app, a OG of 1.107)

Mine measured at 1.096, i had it in primary for two weeks, secondary for four weeks. It got down to 1.019 and i just bottled it the other night. Tasted it from the bottling bucket, and its pretty boozy and just a tad sweet. I'm thinking a month or so from now, it's gonna be great.
