Bigger Minimap Blips (nodes)

[Gonbrok]

Let me introduce myself. I am a multiboxer, with several gathering professions, between different characters. I assume you know what multiboxing is, if not take a look at dual-boxing.com. Anyway, currently I am planning to level a team with mining, engineering and herbalism - the only problem will be the tracking of each minimap!
My setup allows me to have 1 main screen and 3 tiny screens (too small to watch nodes). So far I am aware of the command to scale the minimap, which makes it a suitable size. BUT the nodes on the minimap are not scaling. So my question would be, is it possible to make the nodes on the minimap bigger/scaleable?

I am aware of Blipstick by Tekkub, which changes the textures of the blips, these textures makes the blips smaller. Can you do the opposite?

Thanks for your help!

P.S. If you have any alternative solutions, bring it!
