It sounds like you’re going to be doing the same type of X-axis stiffening mod that quite a few of us have done. I have a video of how I did it in this thread: X-Carve Maintenance/Troubleshooting Videos - Add Your Own!
There’s also a few other stiffening mods you may want to consider, especially if you’re interested in quantifying how well each one works since two of them don’t require milling through the rails. These threads may prove interesting to you:
My feed rates were limited by chatter with the stock 300W spindle. I just upgraded to an 800W GMT spindle and wanted to stiffen the x-rail at the same time. I inserted M5 50mm hex cap bolts vertically in the gap between the x-axis maker slides. They are a perfect fit for the gap. I used 5 bolts spaced about every 6.25".

I used a small washer on top (any larger would interfere with the idler wheels), and used a larger washer on the bottom. It is important to use washers which will not …
I really liked the idea of not having to drill holes through the maker slide on the 30 minute x-axis mod (https://community.inventables.com/t/a-30-minute-x-axis-mod-to-reduce-chatter ) but thought I could take it to the next level. Rather than using washers to clamp the two rails together, I took a trip to the corner hardware store and picked up two pieces of flat bar aluminum. One piece measuring 1”x1/8”x48” and the second one measuring 3/4”x1/8”x48"
