I know this may be a stupid question but is there a way to reference one Mixin within another.

Here is an example of what I am trying. I'm trying to use the first mix within the second as the line height.

.lineHeight(@sizeValue){
  @remValue: @sizeValue;
  @pxValue: (@sizeValue * 10);
  line-height: ~"@{pxValue}px";
  line-height: ~"@{remValue}rem";
}

	.baseFont(@weight: normal, @size: 14px, @lineHeight: (.lineHeight(2.1)) {
	  font-family: @fontFamily;
	  font-size: @size;
	  font-weight: @weight;
	  line-height: @lineHeight;
	}
