Is it possible to pass the css encoding string to the smaller one as a variable?

I am trying to create a system that will output different font sizes and line heights for every other media query, thus I am facing a problem. Any help would be much appreciated.

Function

.return-size(@size) when (@size = mob) { @media-dev: "max-width: @media-mobile"; }
.return-size(@size) when (@size = xs) { @media-dev: "max-width: @screen-xs-max"; }
.return-size(@size) when (@size = sm) { @media-dev: "min-width: @screen-sm-min"; }
.return-size(@size) when (@size = md) { @media-dev: "min-width: @screen-md-min"; }
.return-size(@size) when (@size = lg) { @media-dev: "min-width: @screen-lg-min"; }

.font-size-media(@size, @font-size, @multipler: 1.5){
    .return-size(@size);
    @media (@media-dev){
    .font-size(@font-size, @multipler);
    }
}

I'm using Bootstrap for my responsive design and the @screen -..- min variables refer to the pixel values ​​when the screen is resized.

The font-size function simply takes the font size and outputs the font size and line height based on a multiplier.

Call (example)

.font-size-media(xs,12);

My main problem is when I pass a string to @ media-dev it outputs in my CSS as a string anyway to break it down into string tags when it gets passed back to font-size-media.

Personally, I would probably write a mixin like this something like (well, sketch mode is on):

.media(@device, @styles) {
    @mob: ~"max-width:" @media-mobile;
    @xs:  ~"max-width:" @screen-xs-max;
    @sm:  ~"min-width:" @screen-sm-min;
    @md:  ~"min-width:" @screen-md-min;
    @lg:  ~"min-width:" @screen-lg-min;

    @media (@@device) {@styles();}
}

.font-size-media(@device, @font-size, @multiplier: 1.5) {
    .media(@device, {
        .font-size(@font-size, @multiplier);
    });
}


(again, not knowing how it can be used, so not optimizing things to death).

For anyone else who comes across a similar problem, I found the answer. ( How to pass property name as argument to mixin less )

.return-size(@size) when (@size = mob) { @media-dev: max-width;@measurement: @media-mobile; }
.return-size(@size) when (@size = xs) { @media-dev: max-width;@measurement: @screen-xs-max; }
.return-size(@size) when (@size = sm) { @media-dev: min-width;@measurement: @screen-sm-min; }
.return-size(@size) when (@size = md) { @media-dev: min-width;@measurement: @screen-md-min; }
.return-size(@size) when (@size = lg) { @media-dev: min-width;@measurement: @screen-lg-min; }

.font-size-media(@size, @font-size, @multipler: 1.5){
.return-size(@size);    
    @media (~"@{media-dev}:@{measurement}"){
        .font-size(@font-size, @multipler);
    }
}


Including ~ is like removing line tags before processing LESS.
