The League of Ireland will break for a fortnight at the beginning of June and Rovers are keen to keep their players active for a week of that period.
Already, there are provisional plans to welcome Swedish side Malmo to Dublin as a return for last November's mutually beneficial friendly, which kept both clubs ticking over during their Europa League campaign when their respective domestic seasons were finished.
Last week, Rovers received an approach from DC representatives, who offered to pay for the Hoops' flights to Washington.
The opportunity for a warm- weather training camp and a match against decent opposition appeals to manager Stephen Kenny.
DC have previously welcomed high level European opposition to their territory in July. However, their domestic break this year has been brought forward to the beginning of June, so they must look to clubs from leagues that are in summer seasons.
Rovers will kick off their Champions League mission at the beginning of July.
