Are these Photoshop script ideas possible?

Hello, I'm looking to get into photoshop scripting but was curious if my ideas are even possible to begin with.
What I'd like to make:


- a hotkey for a specific brush
- a hotkey for alternating between two brush flow settings (e.g. press once = brush flow 20%, press twice = 80%, press again = back to 20%)


Thank you!

- a hotkey for a specific brush

AM code can be used to select a brush by name. 

To avoid problems when the brush is absent one may want to wrap it in a try-clause. 

// =======================================================
var idselect = stringIDToTypeID( "select" );
    var desc4 = new ActionDescriptor();
    var idnull = stringIDToTypeID( "null" );
        var ref1 = new ActionReference();
        var idbrush = stringIDToTypeID( "brush" );
        ref1.putName( idbrush, "Hard Round 123 1083" );
    desc4.putReference( idnull, ref1 );
executeAction( idselect, desc4, DialogModes.NO );

var theFlow = theCurrentToolOptions.getInteger(stringIDToTypeID("flow"));
switch (theFlow) {
case 80:
setBrushToolFlow(20);
break;
case 20:
setBrushToolFlow(80);
break;
default:
setBrushToolFlow(80);
break;
