We have always been like that too, long nights (12 hrs and sometimes more) and short naps. At 15 mths, she would do 75-90 min for her one nap but there is hope. After a rough period around 19 mths, she started napping well almost every day. That has been from 20 mths till now (she is 26 mths). She actually seems to need/want more sleep as she got older than at age 1 and we actually have had weeks with 3-4 days of 2 hr naps! It really is more often 1.5 but we still get 12 at night so at age 2, I feel like that is pretty good. So, it could happen for you and I really hope it does. I can feel your pain about the short naps, we have had many stretches of time where its only 30 min too, and that is just awful. I guess some kids are just good nappers and some aren't.
