No it won't work. Yes, it will mess up the hose.

Instead, run the system longer, perhaps two hours. Then check the soil -- put a trowel in and look -- to see where the water went. Now, make a decision -- run longer still? just right? or too long?

The big advantage of such slow irrigation over other faster ones, is the even moisture throughout the soil.

The basic problem with soaker hose is that eventually the minerals in your water will clog the minute pores of the hose and clog it. You can try flusing it with a solvent, but I find that mine develops its own tiny pin holes over time - maybe because I increased the pressure to solve the problem you note. Eventually, I replaced the soaker hose with drip irrigation, which I find cheaper and less problematic.

Some soaker hose will put water out at the rate of 1 gallon per hour per every 10 ft. of length. This can vary with pressure, length of run and water hardness. You may simply need to give it more time to adaquately do the job. 1 gallon per 10 foot isn't much water.
