The 10-11 jump is quite big, only a little bit smaller than 32-36 or 36-40, so a hypothetical 10-32 won't be any less gappy.
In terms of range 11-36 with a 52 chainring exactly matches the gear range of your 11-25 with 52/36. With 10-32 you'd need a 47 chainring (can't go narrow-wide with odd teeth) to match your current range. For comparison a 11-28 Ultegra cassette is 41g lighter than an 11-32. I don't know how much lighter a 47 chainring is than a 52 but assuming it's proportional to the area of the circle a 47 would be about 22g lighter than a 52 (based on a 117g Ultegra 52 chainring).
So at the very most 47 + 10-32 is going to save ~100g off a 52 + 11-36.
