I have not flashed anything Sprint Sense-based for our phone--only AOSP ROMs. The only outcome I know of (based on others' reports) are from entire Sprint Sense ROM's (recovering from that brick requires Sprint RUU (CSpire will not supply their version) and CSpire radio and twrp backup).
I have no idea, better to ask someone with that same device. For safety I'd advise against flashing it without further information
