I had the same issue, so doing a bit of research
i found you can control the colour and transparency of the text using
statustimer setcolor r g b a (for the text, using 0-255 as values)
statustimer setbgcolor r g b a (for the background)
statustimer sethlcolor r g b a (for the "im about to wear off" color)
(e.g statustimer setcolor 255 255 255 127 for white text with 50% transparency
I was playing around with different transparencies and by the time I found one that let me read my combat skills decently, it was too faint to read while playing normally (Didn't dare test it during the day in valkurm)
In the end, I'd say it would probably be better binding a key as already mentioned, but could do something like bind it to a script that sets the transparency to 0 with a /wait of 10 or 20 seconds, to let you read what you need to read, and then set it back to 255 afterwards.
By altering the transparency instead of loading/unloading, it'll maintain the current timers^^
