I do my weightlifting on extra days (general physical preparedness). That could be up to 4 times a week or not at all, if I haven't got the time or feel really sore. I don't go heavy more than once per week per lift though.
You could also just do them on speed day. Dynamic effort day is supposed to be the day where you take care of technique (multiple sets at low reps... makes sense). So you could use the snatch as your second dynamic lift as I use the deadlift. 6 doubles at 70% weight (it's a pretty explosive lift anyway, so you can use higher percentages than prescribed for the squat) or so in 3-6 minutes. Also, remember to slightly alternate your speed lifts every 3 weeks (full snatch, power snatch, muscle snatch for example) to prevent accommodation.
When I last visited the westside barbell forum there was a strongman training with a WSB template.

Maybe that can give you some ideas on what to do.
About the event training:
You could do some of it on the so called general physical preparedness days (GPP). These days are done 2 or more times per week and supposed to take care of muscular weaknesses or whatever you think you are bad at. So it would be tricep work (bodybuilding) to help the bench, sled dragging for conditioning or just light squats and a little prowler pushing to speed up recovery. For you it could be the tire flip, keg floor to overhead and farmers or something like that. The disadvantage in doing so would be that you couldn't go real heavy but walking/running events, higher reps (that's 8+ for me
) and explosive stuff should be fine.
