I recently arrived upon the scene of a nasty ATV accident. Guy was jumping a 45 tabletop and didn't land successfully. I can't tell you exactly what happened but I can tell you that an aluminum tie-rod was snapped. For Honda tie-rod end (a female fitting), it doesn't make sense to switch to aluminum. No matter how thick throughout the rod, eventually it has to be sized to thread into the tie-rod end. This is where the weakness occurs.

Highly recommend keeping solid steel tie-rods. Steel generally just bends unlike aluminum that just snaps.

This is different for a Yamaha tie-rod where it is a male end. You can make the aluminum tie-rod bigger in diameter from end-to-end since you are just drilling and tapping for threads.

Anyhow, I would think twice about doing this and think about changing back if you already did. This guy only required a trip to the ER so he was lucky I guess.
