That will make your life easier for sure. It is widely accepted on this forum that Intex woefully under-sizes their pumps. I have upgraded my pool to the same pump you have, and found it to be a pretty good fit for me--while you have nearly twice as many gallons to filter.
However, those B type cartridges don't capture the really fine silt/dust that can make the pool cloudy. You may find that you just can't get your pool completely clear, even though the chemistry is all OK. Or, it may be clear in the morning after the pump has been off all night, but as soon as you start swimming it clouds slightly due to the layer of very fine particulates (dust, silt, dead algae, whatever) that settled to the bottom while the pool was still.
One trick I use is to wrap a filter in a couple layers of good quality paper towel, hold the ends on with rubber bands, and run it for a couple hours. A lot of the fine particulates will get trapped in the paper towels rather than passing through the filter and going back into the pool. It kinda wrecks the filter (collapses the pleats so water won't flow through it as rapidly) but that filter can still be rinsed and re-used for the same purpose. I have a designated "polishing" filter that I do this with. I have found those B type filters are quite durable -- I rinse my filters every couple of days, and re-use them for a couple of months. It is more work, but will give you a clearer pool until you upgrade your pump/filter to something good.
