It really depends first of all if you are a demon worshipper, or LHP.
Some LHP would beat you upside the head the same as Solomonic practitioners for not following the program.
It is an interesting idea, but again it depends on your approach.
I cannot speak for the LHP, but Im sure some would approve of your idea.
Some modern magicians, mostly LHP, from on Solomonic methods, as the demons are tormented by the approach.
This is where the demon worshippers would chime in that you dont need a circle, that they find it offensive.
I take it you are talking about Goetia here, right?
Most modern methods, in fact, three great tutorials on Koettings site are a Pentetion Ritual Tutorial, Kindrathes Bulletproof Immersion Guide, and Mike_Bees Evocation Guide. Thats how I started to get involved last time with Bime and Ipos on my teachers idea. I had different folks in mind more suited to help me rebuild my life. The modern methods will basically start you off with a petition ritual. You then fully immerse for two weeks, the strongest the latter week before the evocation. At this point you should be listening to enn chants nonstop, meditating on the sigil, etc. Basically building a portal into your consciousness or your building a psychic bridge with them. Your head will swoosh and you might hear the thunder and ripping of the veil. You might see shadows leaping in your dwelling out of the corner of your eye.
Then there is the Demons of Magic approach, a hybrid approach by calling the Shem Angel ruling over them, and three angel emissaries then you call forth the demon and it will have to comply.
Then there is Hargrove and others that have guided meditations or path workings.
All sorts of approaches. Im not sure what you're trying to accomplish by hosting it on your altar, as the altar is your universe. However, I can see it making sense in a way with talismata.
Hope I made sense and it helps. Other more experienced Solomonic type practitioners might want to chime in, as the circle and triangle is kinda crucial to their art.
