About "come over to somebody"
Discionary says = "To visit somebody for a short time, usually at their home."
But is it sutable to use "come over" when a person comes to somebody's house not for a long time, but regularly by the agreed schedule, for doing or discuss a long-running mutual project?
Is the "over" here more bears the meaning of casual visits, rather than the regular ones?

"It worth to mull it over, but let's put it aside now and discuss when I come over to you next time".
OR
"...we'll discuss when I come to you next time". ?
