I'd agree that the MFL should take priority in having stops at 19th and 22nd instead of the trolley but the MFL tracks are surrounded on either side by the trolley tracks and the MFL is directly under the street. So I think they'd have to sink the trolley tracks for a platform or just get rid of the trolley from 30th eastward and make people transfer to MFL at 30th.
Here you can see the MFL tracks surrounded inside of the trolley tracks:
