Sure. Fusible links are simply a low cost, lower parts
count, convenient substitute for the LONG TIME CONSTANT
current limiter. Fusible links and current limiters target
the battery-driven, hard fault condition.
For your purposes, you can replace ANY fusible link
shown in the drawings with a fuse or circuit breaker
but I suggest that it only adds to cost and labor.
But it's not 'unacceptable'.
I would avoid using fuses lower than 3A for
mechanical robustness concerns . . . in fact,
for airplanes wired with nothing smaller than
22AWG, a 5A fuse is a practical lower limit
for fuse selection.

Bob,
In a recent message, you wrote: " I would avoid using fuses lower than 3A

I am installing an MGL backup ASI+altimeter and the installation
instructions call for a 1A slow blow fuse. I bought a glass tube fuse and
an inline holder.
I do remember what you have written (many times!) about fuses protecting
the wires but opted to follow the manufacturer's instructions. I would love
to hear your thoughts about this situation.

1A slow blow sounds oxymoronic to me=2E=2E=2E
