24"oc Truss question...

Not sure how to post a new thread... so i am piggy backing on this one...

Beginning an renovation of an upstairs bathroom. Took out a small partition wall and now am preparing to tile. Used an endoscope to discover that the joists are of the open web truss style. To make matters worse, these are spaced at 24"o.c.. The sub flooring is 3/4" OSB. Over all the floor does appear pretty stiff, save for one spot near toilet room in between the joists. The first choice of floor covering is tile, and that was the plan. However, this floor's framing does not seem up to par for ceramic tile.

Not sure how to reckon the deflection for truss joists.
These are 15" high and constant of 2x4 material.
Not certain of the span, for sure. However, there is a first floor wall just below it approximately 4' from the exterior wall.

Had a hope that i could simply lay some 1/4 hardibacker atop sub flooring to lay the tile on. With this discovery, it is also clear that that will not be sufficient.
We are concerned about floor thickness. it does transition into carpeted bedroom.

If i were to lay down 3/8" plywood onto of the existing 3/4" OSB, and then either Ditra XL(1/8) or 1/4"hardibacker... would this be sufficient to compensate for the 24"oc truss joist situation? And that will bring the tiled surface up as much as an inch above the carpets surface in adjacent room.

What other options are there, other than to tear up sub flooring, fortify framing, to install new 3/4" PLYWOOD onto of that? The latter option seems like a significant increase in labor and material costs. RAWR

Maybe 'luxury vinyl planking' is the solution.
