Two blades per spindle

[loy44]

Has anyone tried putting two blades on each spindle at 45 degrees to get better mulching action?
I have tried searching but haven't found anything.
I've got a BX 2200 60" MMM and was wondering if this would work. However, don't want to put too much pressure on the spindles and cause bearing failure. Thanks

Do not know about Kubota but MF has a mulching deck (54 inch) for the GC series with two blades per spindle at 90 degrees.
