GD hexagram with hygromanteia and picatrix?

[odrep]

What is everyone's perception of using GD hexagram rituals with Hygromanteia and Picatrix prayers, in a more prayer-style (obviously) method rather than directly conjuring a spirit, since I basically have no paraphernalia or tools right now, just my body and voice? So, for Mercury, for example, instead of calling the angel or spirit intelligence directly due to lacking a scrying medium, table, etc. Basically an approach more like asking for intervention rather than direct contact with the spirit.

With the caveat being that I actually have a specific outcome in mind rather than just communion.

Thanks.
