Provided you have access to Illustrator (and not just the brush files), yes.

In Illustrator, start a new document and drag-n-drop your desired brush into

it.  Save as an SVG and import into Inkscape.

Before you can use the brush object on a path you may need to fiddle with it

a bit because 'Pattern along path' expects a path not an object.  For my

test I had to ungroup the brush and combine it (for some reason 'union' made

the brush complete disappear).  This got me an inverted path (the pattern

was cut out from a solid background) so I had to draw another shape and use

'difference' to get it back to how the brush should have been.

There might be an easier way.
