Hi. I'm new to brewing at home. I have some chemistry background as well as some lab and quality control career experience. I have been making wine from kits for a few years now and I recently hacked a stout kit to make a Cascadian Dark Ale which turned out pretty good. I have a hacked IPA kit bottle conditioning now. I am going to try an all grain half batch BIAB next of 3 gallons. Here is my recipe and directions,
1. 5 lbs(2268 grams) 2 row malt
2. 1 lbs(454 grams) caramel malt 80L
3. 0.4 lb(182 grams) black patent malt
4. 0.4 lbs(182 grams) chocolate malt
5. 0.5 lbs(227 grams) quick oats
6. 0.5 oz cascade hops 60 min
7. 0.5 oz cascade hops 20 min
8. 0.5 oz cascade hops 10 min
9. 1 oz dry hop for 7 days
10. Heat 2 pots one with 9.2 litres (2.43 gallons mash at 156 degrees F) one for sparge with 9.2 litres (2.43 gallons at 168 degrees F)
11. Alternatively mash more grain and add water to primary fermentor until volume is at 3.17 Litres and S>G is at
12. Keep the mash at 152 to 154 degrees for 1 hour.
13. Sparge grain bag at 168 degrees with and boil both pots for 1 hour

My problem is I don't have a pot large enough yet to brew this pre-boil wort of 4 gallons(15 Litres) to fill my 3.17 gallon carboy. Is it feasible to adjust my O.G. higher so I can do a boil with my small pot and top up the primary fermentor which will bring my O.G. back down?
I know I will have a thicker mash, sparge a little less and top up the primary fermentor to about 3.5 gallons to account for trub loss.
Ultimately I will get a larger pot but wondered if this idea I have is possible.
