With an empty weight of 830, and probably about 900 with additional beef up, the max gross could be under 1600 and have a larger payload than the 150. With 1600 max gross, the payload would be 700 pounds!
But consensus standards, which is what LSA uses, are far easier, cheaper, and quicker to achieve than an FAA certification.
The second most common cause of 150 fatal accidents (it seems to me using only ancedotal information, flying into IMC is first) is fuel exhaustion. A 30 gallon tank would be my first choice for improvement. Fly till noon, refuel, then fly until evening.
