Yes, it's possible to trade full-time with a Market Maker Broker. You just need an honest broker
There is NO PERFECT broker.

But come on, no compounding, no scalping, no news trading, trade under 1-3 lots.....what kind of a broker is that, not one I've ever heard of apart from the rogue brokers from Russia or Greece or somewhere (no offence to any Russians or Greeks here by the way!) and certainly not any of the mainstream shops, and most certainly not a broker I would want to trade with!
Granted some of these shops don't make it easy for the trader with their wide spreads and slow quotes, and they understandibly get upset if you're exploiting latency or something, but generally I think they're ok to trade with if you've got a relatively small account.
If a trader is paranoid that bucketshops are out to 'get' them by stop-hunting or other questionable tactics then the obvious choice would be to trade the futures market. Only one problem, then who are they going to blame their losses on
