Will Shimano Deore XT FC-T781 chainrings fit on a standard 4-arm 104/64 BCD spider?

I want to fit these "trekking" 48/36/26 rings to a standard 4-arm 104/64 BCD spider. Not installing the complete FC-T781 crankset.

It looks like the middle and granny are standard, but I can't tell from the outer ring photos.

If the middle is "standard" then the outer ring has to be as it and the middle ring share the same bolts.

XT trekking uses the same spider as XT MTB. so they should be compatible.

More concerned about fitting these ring on other non-proprietary shaped 4-arm 104/64 spiders that have square-ish tabs, ie: Specialized, FSA Pro, etc.

I'm actually trying to get a set of 48/36/24 rings. Not yet married to the FC-T781.
