title: can we use the SCSS css preprocessor in Angular 1.6.6 which is already using LESS as css preprocessor?
body: <p>I want to use LESS as well as SCSS in Angular version 1. 
  Do I need to compile SCSS and stylus files first to CSS and import that into my app? or is there any good alternative?</p>
  
  <p>Background: I have two application, one with Angular 4 and one with Angular 1. Angular 4 is using scss and angular 1 is using LESS. 
  I want to use angular 4 apps inside angular 1 keeping angular 1's look and feel?</p>
