I am currently using the following to combine several (e.g. two) images:
montage a.png b.png -geometry +5+5 -tile 2x1 out.png
I can resize the first image to 200% before the images are combined:
montage a.png -resize 200% b.png -geometry +5+5 -tile 2x1 out.png
However, the following resizes both images:
montage a.png b.png -resize 200% -geometry +5+5 -tile 2x1 out.png
Is there a way within this single command to just resize b.png to 200% before the combination takes place?

You can use parentheses to apply operations selectively, like this:
montage blue.png \( red.png -resize 200% \) -geometry +5+5 -tile 2x1 out.png
You may, or may not, need the slashes in front to escape them depending on your shell/environment.
Here is how it looks:
convert -size 30x30! xc:red red.png
convert -size 30x30! xc:blue blue.png
and your original command:
montage blue.png red.png -geometry +5+5 -tile 2x1 out.png
but with selective enlargement as follows:
montage blue.png \( red.png -resize 200% \) -geometry +5+5 -tile 2x1 out.png
Very French, I feel :-)

try resizing during image read with modifier added in square brackets:
montage a.png b.png"[200%]" -geometry +5+5 -tile x1 out.png

it is also worth mentioning that you can also crop image while reading
