@ericks89,

There is a way, if you use BBPress Signature. 😉 Modifying bbp_get_reply_content filter.

Here an example fetching 3 xprofile fields called Signature, Industry and Type. Change it to your need. Code goes into bp-custom.php or child theme functions.php

function my_bbp_reply_content_append_user_signature( $content = '', $reply_id = 0, $args = array() ) {
	// Default arguments
	$defaults = array(
		'separator' => '<hr />',
		'before'    => '<div class="bbp-reply-signature">',
		'after'     => '</div>'
	);
	$r = wp_parse_args( $args, $defaults );
	extract( $r );

	// Verify topic id, get author id and potential signature
	$reply_id  = bbp_get_reply_id       ( $reply_id );
	$user_id   = bbp_get_reply_author_id( $reply_id );
	
	// Get fields data. Caution: name is case sensitive.
	if(function_exists('bbpress') ) {
		$signature = xprofile_get_field_data( 'Signature', $user_id );	
		$wowi = '<br>'. xprofile_get_field_data( 'Service', $user_id );
		$wowt = '<br>'. xprofile_get_field_data( 'Type', $user_id );
	}
	else {
		$signature = bbp_get_user_signature ( $user_id  );
	}

	// If signature exists, adjust the content accordingly
	if ( !empty( $signature ) )
		$content = $content . $separator . $before . $signature . $wowi . $wowt . $after;

	return apply_filters( 'my_bbp_reply_content_append_signature', $content, $reply_id, $separator );
}

if ( !is_admin() ) {
   // remove the original BBPress filter
   remove_filter( 'bbp_get_reply_content', 'bbp_reply_content_append_user_signature', 1, 2 );
   // add our custom filter
   add_filter( 'bbp_get_reply_content', 'my_bbp_reply_content_append_user_signature', 1, 2 );	
}

May this help. 😉
