Is it possible to cross pollinate watermelons and pumpkins?
It's possible, because they're both in the cucurbitaceae family (pumpkins and melons). Keep in mind you won't see the effects on this year's fruit (if you're trying to cross-pollinate on purpose), since it only affects the seeds from this year's plant (and so you'll only see the result in next year's fruit if you plant those seeds).
This article talks a bit more about cross-pollination:

Have had a brutal 2 weeks of 90+ to 98 Degree heat with H.I. 110+ here in Northern Mississippi. Have been watering every other day the hill/roots. I used the raised bed method. The vines/leaves are closing up/drying. Melons are hanging on so far. Do I need to water the row itself? Have the drip hose to do this. Or, just keep watering the hill or roots? Thanks in advance.
Water is crucial for your plants. You can dig down into the soil and check how far the moisture is below the surface of soil.
