Help needed with floor joist cut for toilet plumbing

I am new to this forum and hope someone can help. During a bathroom remodel we discovered that someone had cut all the way through a floor joist and run the plumbing pipe up through the subfloor. Why I do not know as now the on either side of the pipe is basically hanging in the air, no support. What is the best fix for this? Hanging a whole new 16' long 2x10 joist is not going to work, too many other pipes, hvac, electrical in the way. Would making a sandwich of the joist work - using spacers to bring the width of the joist beyond the 3" drainage pipe on both sides of the cut joist and then using the longest joist we can as a sister joist on either side?

Lets see...

Joist 'A' =======================

Joist 'B'/Pipe ======== @ =========

Joist 'C' =======================

That right? If so, nail or screw a 2x10 scab on either side of the pipe to the good joists (A & C) and have the cut joist (B) butt into those, nailed or screwed of course. Looks something like this:

Joist 'A' =========================
scab................... !!.... !!
Joist 'B'/pipe =====!! @ !!=======
scab................... !!.... !!
Joist 'C' =========================

I will try to find an actual photo of this in my collection. Let me know if you don't quite follow. And don't mind all those periods in the second 'drawing'.
