I have not done it myself, in fact I had to google SLA Industries. Legend I feel has a lot of potential as a system for modern and near future gaming. My suggestion is that you use the Legend RPG for the base rules, and Use Basic Roleplaying to round out the Skills and Equipment that are lacking in Legend. Basic Roleplaying covers more genres and time periods than Legend, but is a little to freeform for my liking. Legend feels more like a complete RPG to me.
I threw together a list of Pulp professions with skill bonuses for Legend that can be easily adapted to modern and near future settings. All I am really lacking is a Techie profession, and the addition of the Computers Skill to several of the existing professions.
